Cyclic Productivity for Horizontal Directional Drilling (HDD) Operation

摘要

Horizontal directional drilling (HDD) is considered as the most applicable and cost effective technology among trenchless technologies known. HDD can be applied in different soil conditions, for deep laying of different pipeline diameter and long drives. From 12 HDD units manufactured in 1984, about 32,135 units were manufactured and sold in 2011. Studying HDD productivity is the first goal of this case study. Using cyclic nature of operation, HDD productivity can be determined by applying MicroCYCLONE simulation. Also, operational cost of project can be estimated. Through the current research, presenting of HDD resources is another goal that was achieved in terms of human and mechanical resources.
